Answer:
A and B
Step-by-step explanation:
1 yard= 3 feet
56/12=4.66667
A is 3 feet
and B is 4.666667 feet
no it wouldn’t be a function
Let’s pick a paperback and a hardback
There are 4 x 6 possible choices
Now pick any three of the remaining 8 books
8C3 = 56
This means there are 4 x 6 x 56 = 1344 selections of 5 books that will contain at least one paperback and one hardback
8C3 means picking 3 from 8 without worrying about order
8C3 = 8 x 7 x 6 / (3 x 2 x 1) = 56
Less than. Because one of the numbers multiplying to make the product is lower than that of the other equation. 7.69*5=38.45 whereas 8*5=40
So this is actually very easy but a fast way is to use photo math
